CUPET Hermanos Diaz Refinery — Cuba
Refinery in Cuba. Approximate location 20.00581, -75.87273.
RefineryCubaCO₂ estimate (modelled)
CUPET Hermanos Diaz Refinery is a refinery in Cuba. Its listed capacity is 22,000 BBL per day. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery. It is operated by Cuba Petróleo SA. By capacity it ranks #2 among 3 oil refineries in Cuba. It emits about 94,476 t CO₂e a year from Climate TRACE. That is 6.0% of the CO₂e from the 7 facilities in Cuba that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 50% below the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1753540.

In context: how this facility compares
At 22,000 BBL per day, CUPET Hermanos Diaz Refinery is around the median refinery in Cuba (22,000 BBL per day). Subsector: oil-and-gas-refining. As refinery, it requires high process heat (typically 200–600°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Refineries heat, fractionate and chemically transform crude oil into fuels and petrochemical feedstocks through energy-intensive distillation and cracking — extremely demanding on steam generation and heat recovery.

Carbon cost and Scope 1 emissions
At its reported 94k t CO₂e/yr (Scope 1), CUPET Hermanos Diaz Refinery carries no domestic carbon price, and its products are not CBAM-covered goods, so there is no border-carbon liability. At the EU ETS reference price (€75/t) the emissions carry an indicative carbon value of €7.1M/yr.
Carbon price: EU CBAM €75/t · EU ETS €85/t, September 10, 2026, refreshed live via Carbon Hub. CO₂: Climate TRACE. Indicative carbon value, not the cash bill — free allocation applies; not compliance advice.

Local climate
CUPET Hermanos Diaz Refinery sits in a tropical savanna climate zone (Köppen Aw), at 20.0°N in the northern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1241 W/m² to ambient — roughly 0.95× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
